The general scuttlebutt is that Nicky's calendar failed to sell in the numbers that she hoped. The fact that Nicky herself won't reveal any sales figures tends to suggest it hasn't gone as well as she expected.
The calendar itself is great - who could argue with a calendar's worth of the gorgeous Nicky posing against the backdrop of spectacular New Zealand scenery? The photographer, Scott McAulay, did a fine job.
The problem with the calendar appears to be in the marketing.
